/Engine/Source/Runtime/Engine/Classes/Sound/SoundNodeLooping.h
Defines how a sound loops; either indefinitely, or for a set number of times. Note: The Looping node should only be used for logical or procedural looping such as introducing a delay. These sounds will not be played seamlessly. If you want a sound to loop seamlessly and indefinitely, use the Looping flag on the Wave Player node for that sound.
